Abstract
A depth camera assembly (DCA) determines depth information within a local area. The DCA may selectively process a subset of data captured by an imaging sensor and obtained from the imaging sensor, such as pixels corresponding to a region of interest, for depth information. Alternatively, the DCA may limit retrieval of data from the imaging sensor to pixels corresponding to the region of interest from the imaging sensor for processing for depth information. The depth processing may include a semi-global match (SGM) algorithm, and the DCA adjusts a number of neighboring pixels used for determining depth information for a specific pixel based on one or more criteria. In some embodiments, the DCA performs the depth processing by analyzing images from different image sensors using left to right and right to left correspondence checks that are performed in parallel.
